Ask HN: How do carriers throttle streaming to 480p resolution?
by akouri on Hacker News.
I have seen that most carriers, by default, have a “stream saver” turned on, which, I am assuming detects when you’re on YouTube or Netflix and automatically throttles your bandwidth to these sites. Assuming these connections are happening over SSL, how are the carriers able to modify the sites to disable users from selecting HD or 4k resolutions?
